Benefits of technology

[0013]Each perforation line may comprise alternating perforation tags and perforations, such that adjacent sheets are connected solely by said perforation tags. Preferably, each perforation line extends substantially in a transverse direction (T), being perpendicular to the longitudinal direction (L) in the plane of the web. The extension of the perforations in the direction of the perforation line is suitably greater than the extension of the perforation tags in the direction of the perforation line

Problems solved by technology

One problem with known dispensers and their associated webs is ensuring that the web is dispensed in a consistent manner, i.e. that the same length of web is dispensed each time.
The perforation line therefore becomes less able to promote accurate separation of the sheets along its length (i.e. across the width of the web).
As a result, the web can tear at undesired positions, or fail to tear at all.
Another problem associated with dispensers and their webs is that the free end of the web often falls back inside the dispenser, or the web breaks within the dispenser, meaning that a user has to open the dispenser each time, locate the free end of the web and thread it through the dispensing opening.

Embodiment Construction

[0033]FIGS. 1 and 2 show web 100 according to the invention, in a partially unfolded state. The web 100 may be e.g. a tissue or a nonwoven web. The web 100 is a strip of generally planar material, with a primary extension in a longitudinal direction (L). The web is defined by first 101 and second 102 longitudinal edges and first 103 and second 104 ends. Typically, the web 100 typically has a length (the extension in the longitudinal direction) of between 10 m and 500 m. For tissue webs, the web preferably has a length of between 10 m and 400 m, while for nonwoven webs, the length is preferably between 10 m and 100 m. The web has a secondary extension in the transverse direction (T); i.e. a width, which typically lies between 10 cm and 100 cm, preferably between 20 cm and 50 cm, more preferably between 20 cm and 30 cm. The longitudinal edges 101, 102 are generally parallel to each other, as are the first and second ends 103, 104.

Abstract

A web, such as a tissue or nonwoven web. Perforation lines in the web define sheets. The web is folded before being rolled or stacked, such that the intersection of the perforation lines and the folding line provides reliable dispensing. The web in roll or stack form, a method for forming the web, and a dispenser adapted for dispensing the web are also described.

Description

TECHNICAL FIELD[0001]The present invention relates to a web, such as a tissue or nonwoven web, and a dispenser for said web. The invention also relates to the web in the form of a roll or stack, and methods for making the web, the roll and the stack.BACKGROUND OF THE INVENTION[0002]Dispensers for webs, such as tissue paper or nonwoven webs are well known. They can be divided into two general types. The first type comprises stack dispensers in which the web to be dispensed is stored in stacks inside the dispenser, and adjacent sheets of the web are interfolded or joined in some way. Dispensers of the second type are roll dispensers, in which the web to be dispensed is stored in the dispenser on a roll.[0003]WO 98 / 37794 discloses rolled and folded napkins, which can be dispensed individually or two or three at a time as desired, depending on the dispensing method.[0004]US 2006 / 0184148 describes folded fibrous structures, which may be in roll form.[0005]GB 2 400 596 describes a roll of...
